A Study On Rhizosphere Soil Moisture And Canopy The Micro Domain Factors On The Impact Of Interaction On Grape Photosyutbetic Metabolism Under Two Planting Pattern Curtain

The test with 2 years of the Vitis vinifera L.’Jinya and the red grapes as test materials, Under the condition of water control strictly, through the determination of grape rhizosphere soil moisture, canopy the micro domain factors and the photosynthetic indexes of grape leaf to study the main factors influencing the grape photosynthetic metabolism in the different planting models, to explore the grapes photosynthetic and potential relationship with soil moisture change under different habitat, to seek feasible way to produce high quality grape water saving. The results show that;(1) The variation of soil moisture in different planting patterns of grape. The grape rhizosphere soil moisture with deep-furrowed cultivation decrease slowly, extend the grape water cycle obviously, has the effect of water saving.(2) Canopy the micro domain factors in different planting patterns has a difference. Deep-furrowed cultivation can improve the summer grape leaves appropriately curtain light and temperature and humidity conditions, reduce blade wind velocity, to provid suitable environmental conditions for photosynthetic production.(3) Wind speed and light radiation are the main factors affecting soil moisture decrease. Soil moisture can directly affect the photosynthetic metabolism, also can act by changing leaf temperature and humidity conditions indirectly affect photosynthetic metabolism of grapes, overall consideration, under two planting patterns, soil moisture and wind speed are the dominant factors of photosynthetic metabolism. The photosynthetic physiological with deep-furrowed cultivation affected by leaf curtain light, temperature, humidity is higher than the ground to plant, and is affected by soil moisture and wind speed is lower than the ground to plant.(4) The grapes’cultivation average photosynthetic metabolism with deep-furrowed is higher than the ground to plant, and maintain a long cycle. Deep trench planting suitable leaf screen environmental conditions and higher soil moisture is the main cause of its photosynthetic higher levels.(5) Under the comprehensive factors, Deep groove planting soil moisture threshold of 41.76%, the ground planting is 52.60%, Deep groove below the ground. Deep groove planting can maintain efficient photosynthetic physiological metabolism of grapes under low soil moisture, further up the effect of water saving. Soil moisture under different ecological environment conditions of different threshold, the soil moisture variations in threshold with deep-furrowed cultivation below ground planting, more stable.
